Full Description

This study was undertaken to gain a better understandingof short-term atrazine concentrations in drinkingwater by developing an intensive sampling programover a seven-month time period. Samples were analyzedby a commercially available enzyme-linkedimmunosorbent assay (ELISA) test method. Althoughthe authors found that the test kit approved by the USEnvironmental Protection Agency was not accurate formany of the waters tested because of water matrixinterferences, they were able to observe trends inatrazine occurrence.Surface waters were found to be more vulnerable toatrazine contamination than were groundwatersources, peak atrazine occurrence corresponded well torunoff, and some drainage basins were more susceptibleto atrazine occurrence than others. In addition,findings demonstrated that atrazine can be effectivelyremoved using activated carbon in granular form, powderedform, or both. Specific knowledge of atrazineoccurrence will help utilities control atrazine moreefficiently and reduce treatment costs by applying activatedcarbon during peak atrazine periods. Includes 19 references, tables, figures.
